Time to do the exhaust on my TII. I'm going with those HKS Carbon-Ti mufflers (3" inlets) and custom piping, I'm sure the shop can do a true deal set up. Now I have some questions. I want to ditch all the cats and do full 3" piping all the way back so I need a DP but what company?
Also will I have to worry about boost spiking with a 3" exhaust and basically no other mods? I do have an FCD in place BTW.
